Application August 12, 1954, Serial No. 449,481 1 Claim. 01. s 41 A Thisinvention relates to novel shaving apparatus more particularly a razorprovided with lubricating means whereby a razor may smoothly pass overthe skin to be shaved.

"Optimum shaving results aregenerally obtained from the use of so-calledwe't shaves wherein the area to be shaved is first thoroughly moistened;then has applied thereto a shaving cream, and after a brief periodduring which the shaving cream thoroughly wets the hairs to be cut, arazor is employed to shear oif the hairs as close as possible to theskin. Often the same skin area is traversed a plurality of times by therazor. As is apparent, with each traversal of the blade less moistureremains on the skin and thus the friction between blade and skin isincreased. This may be slightly avoided by a continuous wetting of theblade between each shaving stroke by holding under a faucet. This is,however, awkward and time consuming, and does not really serve tomoisten and lubricate the skin.

It is with the above problems in mind that the present construction hasbeen evolved, a construction providing a shaving apparatus which insuresa pre-moistening of the area of traversal of the razor blade.

Accordingly, it is a primary object of this invention to provide a novelrazor construction.

It is a further object of this invention to provide apparatus which maybe used in conjunction with existing razors to aid in their function byinsuring a moistening of the area to be shaved.

Another object of this invention is the provision of a razorconstruction which permits the continuous moistening of the areatraversed by the blade in advance of said blade whereby friction betweenskin and blade is minimized.

It is also an object of this invention to provide a razor constructionpermitting the application of any desired shaving preparation such aslotions, creams or the like during the shaving operation.

A further object of this invention is the provision of aself-lubricating razor construction economical in production, having fewparts, and requiring minimum maintenance.

These and other objects of the invention which will become apparent fromthe following disclosure and claims are attained by provision of aflexible container having a nozzle and forming a part of the handle fora razor. The nozzle of said container is directed towards the faceimmediately before the blade, during its normal traverse.

This construction will be more specifically pointed out in the followingspecification taken in conjunction with the drawings wherein:

Fig. 1 represents a perspective view of a conventional safety razor withparts broken away to reveal the provision of the novel elements formingthe gist of this invention.

Fig. 2 is a side .view of a safety razor provided with an auxiliarylubricating apparatus with parts broken away to show the connection.

Fig. 3 is a perspective view of the auxiliary apparatus showninFig. 2. e

Fig. 4 is a crosssectional view showing how the instant inventiveconcept may be further embodied in razor construction. t

The embodiment disclosed in Fig. 1 reveals a safety razor 10 havingthe'conventional safety razor head 11. The head memberll forms no partof this invention and is merely indicated in block outline- The handlemember 12 comprises hollow barrel portion 13 provided with aperture 14and bushing'15'. The top portion of the handle is not here illustratedand is of any conventional type suitable for coaction with razor .head;11. Within the barrel a flexible plastic cartridge 16 of vinyl plasticor the like having a nozzle 17.i's provided. 1 The toprpo'rtion ofthevbarrel is closed 01f and-the bottom portion closed by closure member18. This closure member has a .portion 19 adapted to be press fittedinto hollow barrel .13 engaging key22, and portion 20 adapted for screwengagement' for closing cartridge 16. A spring member 21 is suitablyfastened within barrel 13 and extends as seen in Fig. 1 along a sidewall of the cartridge 16. Push button 25 having flattened portion 26 inengagement with spring 21 is positioned within bushing 15.

In operation the above described construction may obviously be employedas a conventional razor with the additional features flowing from theabove described construction details applicable to enhance thisfunction. Thus cartridge 16 having lower closure 18 removed is fil-ledwith any desired shaving preparation, water, cream, lotion or the like.Closure 18 is screwed into position in the cartridge 16 and thecartridge 16 is inserted into barrel 13 with nozzles 17 in alignmentwith aperture 14 at which point portion 19 of the closure will besecuredly engaged in barrel 13 with key 22 engaging portion 19.Thereafter while shaving, pressure applied to push button 25 results ina partial collapse of cartridge 16 expellingv its contents throughnozzle 17 unto the shaved area in the path of traverse of head 11.

It is apparent that nozzle 17 may be arranged to direct the contents ofcartridge 16 in any desired direction, and if for example the cartridge17 is filled with water the nozzle may be directed against the bladeedge to rinse same.

The construction disclosed in Figs. 2 and 3 reveals an embodiment of theinstant inventive concept permitting application to existing safetyrazors, thus a cartridge element 30 formed of the above disclosedflexible plastic material is formed with cylindrical groove 31. Nozzles32 are formed in the front face of said cartridge. A removable closurecap 33 is suitably positioned in said cartridge.

In use this cartridge is adapted for engagement with the handle H of anyconventional safety razor and as seen in Fig. 2 is positioned withnozzles 32 directed so that the contents of said cartridge may beexpelled in the path of razor blade travel. The cartridge as above maybe filled with any suitable material which is expelled through nozzles32 upon squeezing of said cartridge, which is flexible. Though theconstruction here revealed is applied to safety razors, obviously thepresent inventive concept may be embodied in a construction for use withregular razors.

The construction revealed in Fig. 4 reveals an embodiment of the hereindisclosed inventive concept in which the handle element 40 is made of aflexible material and is provided with a hollow inner portion 41 andnozzle 42 whereby it may serve as the above disclosed cartridge. Aclosure member 43 here shown as tapped, but suitable for fastening inany other desired manner, is employed for closing oif the cartridgeformed by the handle. The

Y PatentedApr. '30, 1957 uppermost portionof'thehandle element is hererevealed i as tapped for engagement with a screw from the razor head butmay obviously be, conjoined with said head in any other desired fashion;

K Itwill be apparent: that in operation thehandlecartridge member isfilled through closure 43'with any de.-..

sired material for shaving purposes,' which may then be expelled by:squeezing the handle through nozzle 42, to

facilitate the shaving operation as discussed.

It is thns seen that a razor construction has here been presented whichwill permit the facile use of any desired shaving preparation during theshaving operation and permits theareato be shaved to be maintained in amoistened condition at all times, thereby lubricating the patlr oftravel of therazor and eliminating any' unwanted 4 a hollow barrel,a'resilient walled cartridge eccentrically located in said barrel andhaving a nozzle, said barrel having an opening located adjacent the topof the handle element and communicating with said nozzle, an elongatedspring having one end connected to an inner wall of said barrel andanother end engaging a wall of said cartridge, a removable closuremember closing the bottom ends of said barrel and said cartridge, and apush button 1 extending through another opening formed in said barreland having aninner portion engaging said other end of the spring, saidother opening of said barrel being located on a side of the barrel whichis substantially diametrically opposite the side upon which thefirst-mentioned opening is located.
